DairyTalk 81: DNA Roadmaps - How Genetic Markers Guide Smarter Breeding - by Helmut Demmelhuber
Breeding begins in the genome.
In this DairyTalk episode, Helmut Demmelhuber explains how genetic markers - from haplotypes and casein variants to polled genetics - are transforming modern cattle breeding.
Haplotypes (HH1–HH6) prevent fertility losses, A2A2 and BB casein improve milk and cheese yield, and polled genetics (pp/Pp) promote welfare and safety.
Understanding these DNA markers means breeding with precision - and turning science into sustainable success.
